I have a project with about 10 MOV files - some are 264, some uncompressed and then some MP4. A second track has a title credit that is overlayed on each of the main video file - fades in for about 3 sec then fades out. The project played fine with the overlays showing as overlays when I first played it through on the timeline, but now, 1 minute later, I do not see any of the video files and only the title credits overlays playback. Nothing at all has happened to the system, the drives, the project - in fact I simply left the room to whiz. What on earth would cause this and what is the fix?
Thanks,
